SPECIFICATION forming part of Letters Patent No. 285,222, dated September 18, 1883.

(No model.)

To @ZZ whom, it may concern:

Beit known that I, ONsIME BRUNELLE, a subject of the Queen of Great Britain, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain newv and useful Improvements in Securing, Scratching, and Buffiug Wheels, of which the following is a specification.

My invention relates to an improvement in a buffing and scouring wheel, the object of which is to provide a device for cleaning and scouring castings and other metals, also for polishing and buffing the work, all of which will be fully explained in the description of the accompanying drawings.

Figure l is a central vertical section of my improvement on line y y, Fig. 2. Fig. 2 is a front elevation of the saine. Fig. 3 is a sectional elevation on line r ai, Fig. 1,'with the iront disk removed.

In cleaning castings or similar material preparatory to electroplating or other treatment, wire has been used, and great difculty has been experienced in itsuse, owing to the breaking of it; also, by the rapid wearing of the wires, the cleaning-wheel soon becomes worn out.

I have devised an improved method of constructing' the cleaning and polishing wheel, which holds the wires in a better manner and prevents their liability of breaking oif in. use. My invention also allows the wires to be easily replaced, which is accomplished by means of a removable disk, which also may be adjusted to any regulated thickness of wheel employed. A represents the driving-shaft, upon which K the disks of the wheel are mounted.

B represents a metallic disk, which is provided with a hub, b, which may be keyed to the shaft, if desired, to provide greater security against the disk and its hub rotating on the shaft.

C represents a removable disk, which is pierced at the center with an eye, which iits upon hub b of disk B.

D represents a washer, and E anut tapping upon the spindle a, for securing the disk C in position on the hub b, and the washer and nut also serve to clamp the disk B against the collar A on the shaft. The washer D may be grooved out, so as to tit over hub b, having an annular exterior iiange meeting against the surface of disk C, so as to allow a closer adjustment of the said disk, but the form herein shown is the best.

F represents a circular seriesof pins,which are rigidly secured to the disk B.

Disk C is provided with a circular series of holes, into which the pins F4 project when the two disks are. put together, as shown.

G represents a bundle of wire strands, which are looped around the pins F. The pins being round and the bundles G being made to fill the space between the pins furnish a very superior means of holding the wire and avoid.- ing danger of its breaking. As the strands of one bundle assist to support the strands of another bundle, they each form a iiexible support for the other, avoiding a rigid clamp or bight of any particular portion of the wire near theholdingpoint, and allow thewires to yield under the pressure to which theyv are subjected in use without danger of breaking. These strands assume the position shown at H, Fig. 3, when they are subjected to pressure for acting von the surface of inet-als. When the wires are worn out, they can be readily replaced at sin all cost and a great saving effected. The disks and pins and Inode of attaching them to the shaft may be employed in the application of the wheels as butfing-wheels, and flexible iibrous. materials-such as twines looped around the pins, instead of the wires, and such a construction would be included in the second clause of claim herein. The wires and twines, in the motion of the wheel, are caused by centrifugal force to move radially therefrom,` thus presenting at the point of contact with the obj ect to be polished orscoured a long flexible semi-yielding scouringsurface.

I claimw l. A scouring o r polishing wheel composed of a shaft, A, lixe'd disk B, series of pins F, disk C, bundles of flexible wires G, looped around the pins, and means for confining the disks on the shaft, substantially as described.

2. A polishing-wheel composed of a shaft, A, fixed disk B, series of pins F, disk C, bun- Q wenn@ dles of flexible fibrous material looped around l In testimony whereof I have hereunto set the pins, and means for confining` the disks 0n my hand. v the shaft, substantially as described. y
